DM-14B & DM-14C User’s Guide N.B. With reference to fig. 8, the NETWORK name you can read in the centre to the right, e.g. NETNAME=SKY, is the NET.ID table transmitted via satellite by the operator and which the instrument reads by extracting the information from the MPEG data. However, the prog. name, read in the centre to the left under the word MENU, e.g. PROG NAME: SKY1, is the one you, or your dealer, has pre-stored and can be varied only using a PC, opt. (see page 19). N.B.
